This is a big topic you are not going to find a single tutorial to cover it all. Break it down into topics like rendering meshes and search for thinks like vertex buffers or VBO. Get to understand how to render a simple mesh like a box first then move to non-animated objects like .obj or .x. Finally attack boning/skinning.

Before I can suggest tutorials I need to know what you know about OpenGL. Have you programmed using it before?
